WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 779,978, dated January 10, 1905.

Application filed September 23, 1904. Serial No. 225,676.

To all whom it may concern Be it known that I, THEODORE R. TIMBY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in WVater-VVheels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- IO pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to reaction waterwheels, which will be hereinafter more fully described in the specification, illustrated in the drawings, and particularly pointed out in the claims.

One object of my invention is to increase the power and force of the wheel by additional weight. I accomplish this object by superposing on the wheel or its casing a waterchamber of suitable form and size connected to the chamber of said wheel by one or more 2 5 apertures to permit the flow of water therethrough to the chamber of the wheel.

A further object of my invention is to increase the pressure and outflow of the water in the lower chamber by discharging therein 0 with great force the water from the superposed chamber, thereby accelerating its moveinent and increasing the power of the wheel. This water-chamber is rigidly secured to the water-wheel or its casing by suitable fasten- 3 5 ing devices. I prefer to combine the waterchamber above mentioned with a reaction water-wheel such as shown in Letters Patent No. 4,845 granted to me November 10, 1846, and hence I will describe and illustrate it as 0 applied thereto; but it can be readily applied and adapted to any water-wheel of that type.

In the accompanying drawings, Figure 1 is a side elevation of a water-wheel embodying the salient features of my invention. Fig. 2

4 5 is a vertical longitudinal section of the same. Fig. 3 is a plan view, in partial section, of the dividing-plate between the water-chamber and the water-wheel; and Fig. 4 is a plan of the wheel with the water-chamber removed.

Similar letters of reference indicate like 5 parts in the several figures of the drawings.

Referring to said drawings, A represents the bottom plate, and B the top or dividing plate of the wheel, which are connected to each other by means of the two flanges or rims D, which extend each from the diameter of the central aperture E of the dividingplate B to the outer periphery of the two. Generally I cast these flanges or rims with the lower plate A and bolt the upper plate to them, or the whole may be cast in one piece or each piece cast separately. The end (Z of each flange or rim, or that part which constitutes the outside of the issues, is made separate and attached in position by screws or other means, so that they can be removed and others of different length substituted when it is desired to increase or decrease the area of the issues.

The bottom plate A instead of being flat is raised in the middle, forminga regular curve from the shaft O, which is connected thereto, to about one-half of the radius, and the dividing-plate B from its inner periphery outward has a corresponding curve E, so that as the water descends from the flume K it is gradually deflected, so as to impinge with its full force on the inner surface of the rims or flanges D, which being eccentric present surfaces gradually receding from the center, so that the pressure outward exerts a considerable force to turn the wheel in the direction of the arrows shown in Fig. 4c.

The plate B, which forms the dividingplate between the water-chamber F and the water- 5 wheel below, is provided with an upwardlyextending neck or hollow column B, preferably formed integral with said plate B, and said neck or column is provided with apertures or openings 5 around its circumference 9 for the passage of water therethrough into the water-chamber F, as will be more fully hereinafter referred to.

The water-chamber F is formed of the top plate G and inclosing rim or flange G, the lower part of which is adapted to be secured to the water-wheel or its casing by suitable fastening devices a, the central part of said plate having a circular opening formed by the upwardly-extending neck or hollow column Ur, which is adapted to snugly fit upon the circular neck or column B of the dividing-plate B, as fully shown in Fig. 2 of the drawings. The water-chamber thus formed is provided with two inner walls or flanges H H, which divide said chamber into two compartments, and each compartment has an aperture Iextending through the dividing-plate B into the water-wheel below, as more fully shown in Fig. 3.

The water-wheel is rigidly secured to the shaft C at the bottom of the same, and the superposed water-chamber in turn is rigidly secured to the water-wheel, so that they revolve together, said shaft resting and being adapted to turn upon the spindle L, while the upper part of the neck or hollow column Gr of said water-chamber is adapted to revolve upon the lower end of the cylindrical flume K, which leads from a bulkhead or other suitable source of supply.

As herein shown and described, my invention consists of a superposed water-chamber combined with a reaction water-wheel, to

which it is rigidly secured. Its operation will 1 be as follows: The water being released from the bulkhead or source of supply flows down through the flume K to the chamber of the water wheel, where it is deflected by the flanges D, (shown in Figs. 2 and 4,) which be ing eccentric to thewheel cause the water to flow outward toward the issues D with the effect of causing a recoil in the wheel and rotation thereof in the opposite direction from the flow of the water. At or about the same time that the water fills the lower chamber the superposed chamber F is also filled from the flume K through the apertures b in the neck of the hollow column B, the water in said chamber being revolved with the chamber by means of the partitions H H acquiring a centrifugal force due to its speed of revolution. At its points of escape through the openings I in the dividing-plate B the water ejected therethrough exerts a pressure within the wheel proper due to its centrifugal force acquired in the subchambersff, thereby materially augmenting the force operating upon the flanges D of the wheel. This augmenting force is particularly effective, because it is applied to the wheel where the pressure therein is measurably reduced by the proximity of the issues or points at whicli the water escapes from the wheel. It will be seen that the water as it issues from apertures I under centrifugal force affects the water beneath more or less as an injector and that the additional force imparted to the wheel is that of a column of water of the area of the apertures and having the same head as the water in flume K. hen the motion of the water-wheel is stopped by cutting off the water-supply or otherwise, the water in its chamber flows out, and the water in the-su perposed chamber also flows down and out through the apertures I, and thereby both chambers are emptied and freezing of the water prevented.

Having thus described my invention, I claim as new and useful 1. The combination with a reaction waterwheel, of a superposed water-chamber having a closed periphery, substantially as and for the purpose specified.

2. The combination with a reaction waterwheel, of a superposed Water-chamber having a closed periphery automatically filled with and emptied of water, substantially as and for the purpose specified.

3. The combination with a reaction waterwheel of a superposed water-chamber having a closed periphery and provided with inlets and outlets for automatically filling it with water and discharging said water therefrom, substantially as specified.

4:. The combination with a reaction waterwheel, provided with an inlet and outlets for receiving and discharging water, of a superposed water-chamber having a closed periphery and having inlets and outlets for automatically receiving water from the source of supply and then automatically discharging the water therefrom into the water-chamber of the water-wheel, substantially as specified.

5. The combination with a reaction waterwheel provided with a water-inlet and wateroutlets, of a superposed water-chamber having a closed periphery and provided with automatic water inlets and outlets for receiving and discharging water,substantially as specified.

6. The combination with a reaction waterwheel comprising a water-chamber having eccentric flanges therein and issues or deliveryopenings, of a superposed water-chamber provided with inlet and outlet apertures and division-flanges, substantially as and for the purpose specified.

7. The combination with a reaction waterwheel, having a curved bottom plate A, a top or dividing plate B, flanges D, issues D D, power-shaft C and flume K, of a superposed water-chamber 2, having its bottom formed by dividing-plate B, with apertures I, I, therein, a top plate G and inclosing ring Gr having a central opening, a neck B, apertures there in b, and fastening devices a a, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

THEODORE It, TIMBY.
